There is a collection of utilities for working with SWF files called SWFTOOLS. You can grab the Windows binary from the Download page.
有一组用于处理 SWF 文件的实用程序，称为SWFTOOLS。您可以从下载页面获取 Windows 二进制文件。
One of the tools in this package is swfdump, which can tell you the dimension of an SWF file. It also can produce the proper HTML code for embedding (output from my Linux box):
此包中的工具之一是swfdump，它可以告诉您 SWF 文件的尺寸。它还可以生成用于嵌入的正确 HTML 代码（来自我的 Linux 机器的输出）：
# swfdump -X flash.swf
-X 724
# swfdump -Y flash.swf
-Y 147
# swfdump -E flash.swf
<object type="application/x-shockwave-flash"
data="flash.swf" width="724" height="147">
<param name="movie" value="flash.swf"/>
<param name="play" value="true"/>
<param name="quality" value="high"/>
</object>

Open it from your hard drive using Flash player -double click it- and then use JR Screen Rulerto look at its dimensions. If it happens to open in full screen mode just press ESC ;)
使用 Flash 播放器从您的硬盘驱动器打开它 - 双击它 - 然后使用JR Screen Ruler查看其尺寸。如果它碰巧以全屏模式打开，只需按 ESC ;)

SWF files have a header right at the start where the frame size in twips is stored as a RECT structure. When the image is played back at 100% scaling, there are 20 twips to a pixel.
SWF 文件在开头有一个标题，其中以缇为单位的帧大小存储为 RECT 结构。当图像以 100% 缩放比例播放时，一个像素有 20 缇。
